Acoustic Mullion Caps

A standard mullion has an STC rating of 28.  If left exposed, sound transfer between rooms will be a problem due to the poor noise deadening performance of the mullion

Mull-It-Over Mullion Trim caps increase the STC rating at the mullion to minimize sound flanking.

Fire rated sound barrier Mullion Trim Caps are also available.
